Application filed November 11, 1905. Serial No. 286,932.

To all 2071,0711 it may concern:

Be it known that 1, CHARLES J. LARSON, a citizen of the United States, residing at Argyle, in the county of Marshall and State of Minnesota, have invented a new and useful Hay-Rack, of which the following is a specification.

' This invention relates to hay-racks and similar devices, and has for an object to provide a device of the class embodying new and improved features of convenience, utility, and efficiency.

A further object of the invention is to pro vide improved means for loading and unloadin hay and similar material from a rack or ot er conveyance.

A further object of the invention is to provide improved means for supporting the rack under the added weight and strain incident to operating the device.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any of 0 the advantages of this invention.

In the drawing is shown a perspective view of the improved unloading device mounted upon a rack and wagon of ordinary construction.

In its preferred embodiment the improved hay-rack forming the subject-matter of this application comprises a rack of any ordinary and approved size, form, and construction and shown at 1 as a conventional hay-rack mounted upon a wagon. At one end, preferably the rear, is erected a mast 2, secured at its foot in any approved manner, as by the bolts 3 and braces 4. At its upper extreme the mast is formed cone-shaped, as at 5, with a stud 6 extending from the apex and axial to the cone. The stud 6 is loosely embraced by a ring 7, to which are secured the reverselyinclined brace-rods 8, which in turn are pivotally connected by the clips 9 with the boom 10. The boom 10 is disposed with its middle point adjacent the mast and one end 11 held from an upward movement by a chain or similar cable 12, the length of which may be varied in any approved manner, as by the grab-hook 13 to raise or lower the end 11.

At the end 14 opposite the end 1 1 a pulley 15 is secured to the boom and a cable 16 passed therethrough and provided at its end with a hay-fork or other means for engaging a load, as the material 17. The cable 16 passes through a pulley 18, secured to the boom intermediate its ends, thence downwardly througn a pulley 19, secured ad acent the foot of tne mast, thence laterally oi the rack, through a pulley 20, and is connected to a means for applying power, as the whifiietree 21. At the end 11 of the boom is also secured a rope or other cable 22, by means of which the boom may be rotated about the mast to properly position the load-engaging means.

As the end of the rack will be subjected to a very considerable strain and added weight when the device is operated, standards 23 are hinged, as at 24, to one of the cross-pieces of the rack, as 25, and so arranged as to drag upon the ground when the wagon is in motion and to support the rack when at rest.

The device may be used for loading hay or other material upon the rack or for unloading from the rack to a stack or the like, and it is believed that from the foregoing description the use, operation, and advantages of the device will be fully and clearly understood.

Having thus described the invention, what is claimed is 1. A device of the character described comprising a vehicle-body, a mast rigidly upstanding from the body and having a tapered end, a stud upon said end, a ring rotatably mounted on the stud, aboom, brace-rods connecting the ring and boom and supporting said boom, load-raising means connected to one end of the boom, and adjustable means secured to the other end of the boom and to the mast for holding the boom at a desired angle to the mast.

2. A device of the class described comprising, avehicle-body, a mastrigidly upstanding from the body and having a conical upper extremity with a stud rigidly extending from its axis, a ring embracing the stud and bearing upon the conical surface, reversely-inclined brace-rods carried by the ring, a boom carried by the brace-rods and rotatable about the mast, and means to raise a load from the end of the boom.

3. A device of the class described comprising, a vehicle-body, a mast rigidly upstanding from the body and having a conical upper extremity with a stud rigidly extending from ITO its axis, a ring loosely embracing the stud and bearing upon the conical surface, reverselyinclined brace-rods carried by the ring, a boom carried by the brace-rods, means connecting one end of the boom and the bottom of the mast, means to vary the length of the connection and raise and lower the end of the boom, means carried at the other end of the boom to raise and suspend a load and means to swing the boom about the mast.

4. A device of the class described comprising, a vehicle-body, a mast rigidly upstanding from the body and having a conical upper extremity with a stud rigidly extending from its axis, a ring loosely embracing the stud and bearing upon the conical surface, reverselyinclined brace-rods carried by the ring, a boom carried by the brace-rods and disposed with its middle point adjacent the mast, a

cable connecting one end of the boom and the foot of the mast and embodying means for varying the length, a cable suspended from the other end of the boom and carrying means I or engaging a load and passing through properly-disposed pulleys and provided with means for attaching power, a cable attached to one end of the boom and adapted as means to rotate the boom about the mast, and standards hinged to the under side of and to support the body.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES J. LARSON.
